The Reduction in Computation Time in the Color Image Decomposition with the Bidimensional Empirical Mode Decomposition Approach

This paper presents two different approaches in color image decomposition domain with Bidimensional Empirical Mode Decomposition (BEMD). The first approach applies the BEMD on each channel separately and the second is based on interpolation of each channel in the sifting process. The comparison of two approaches shows the same performance of each approach in terms of visual quality, but they do not provide the same results in execution time which presents the most important criteron in real time applications. It was shown that the second BEMD approach based on interpolation of each channel in the sifting process, gives a gain in the point of view the execution time.
